为了研究密肋复合墙结构筏板基础基底反力的分布规律,对基底反力进行了现场原位测试。在现场测试数据的基础上,绘制出各轴线的基底反力分布曲线,得到密肋复合墙结构筏板基础基底反力的分布规律以及影响基底反力分布的因素。分析结果表明:密肋复合墙结构筏板基础基底反力的分布与地基土的组成构造、基础的横纵刚度及上部结构与地基基础的共同作用有关,在纵向轴线上基底反力实测曲线不呈现规律性的马鞍形或凹抛物线形分布,在横向轴线上基底反力实测曲线则呈现明显的马鞍形分布。 In order to study the distribution law of the base reaction force of the raft base in the multi-ribbed composite wall structure, the in situ reaction of the basement was tested in situ. Based on the field test data, the reaction force distribution curve of each axis was plotted, and the distribution law of the reaction force of the raft base and the factors affecting the reaction force distribution were obtained. The analysis results show that the distribution of foundation reaction force of raft foundation in multi-ribbed composite wall structure is related to the composition of foundation soil, the transverse and longitudinal stiffness of foundation and the combined effect of superstructure and foundation. The measured curve of substrate reaction force on longitudinal axis is not Showing a regular saddle or concave parabolic linear distribution, measured in the lateral axis of the reaction force showed a significant saddle-shaped distribution curve.
